Title: Improvements in or relating to measurement of low energy ª†-radiation
IPC: G01T1/10
Filed: 1966-06-27
Abstract: 1,146,646. Dosimeter system. KERNFORSCHUNG FUER G.m.b.H. June 27, 1966 [June 28, 1965], No.28697/66. Heading G1A. [Also in Division H5] The proportion of y-radiation which is below 45 kev in a y-ray spectrum which also includes higher energies, is measured by subjecting to the overall radiation two dosimeter elements, e.g. of phosphate glass, which are enclosed in envelopes having differing degrees of absorption to the yradiation in the range below 45 kev, measuring the doses received by the elements by causing them to fluoresce and using the difference in the detected intensities of fluorescent radiation as an indication of the proportion of the dose below 45 kev. The two phosphate glasses may be contained, for example, in plastics and copper foil envelopes, respectively. High energy quantum radiation e.g. 45-80 kev is not measured since this is transmitted equally by both envelopes and cancels out when the difference is taken during readout. Low energy radiation, e.g. below 45 kev, is not passed equally by the envelope materials and if the thickness and absorption properties of these materials are known, the actual dose in the range below 45 kev can be calculated from the difference value.

Title: Improvements in and relating to a Method and Apparatus for the Production of Compost from Household Waste
Inventor: PRAT FELIX
IPC: C05F17/02
Filed: 1966-06-27
Abstract: 1,153,587. Composting. F. PRAT. 27 June, 1966 [30 June, 1965], No. 28719/66. Heading C1B. Household waste is aerobically composted in three stages in a mobile silo which is open at the top, has perforated side and bottom walls closable by external shuttering of Venetian blind type, and has removable perforated air injection tubes. The openings of the perforated walls may form 60% of the area of the walls. A layer of compost product is laid on the freshly charged waste in the silo and a mixture of air and steam at a temperature of 65‹ C. and a pressure of ca. 22 1b/sq. inch is injected into the waste while the shuttering is open. The silo is then exposed to atmospheric air only, with the shuttering half closed. Finally, composting is completed with the shuttering completely closed. Total composting time may be four days. Coarse material produced by screening the composted waste is freed from metal, crushed, recombined with fine material, and the mixture freed from plastics material. A plurality of silos in series are treated semi-automatically.

Title: Improvements in apparatus for electrically testing the thickness of thin layers
IPC: G01B7/06
Filed: 1939-10-26
Abstract: 535,105. Measuring thickness. TAIT, W. H., and CHALMERS, B. Oct. 26, 1939, No. 28763. [Class 40(i)] [Also in Group XXXVI] In electromagnetic apparatus for measuring the thickness of thin layers which are arranged to form a gap in the magnetic circuit of a transformer, variations in the magnetic properties and dimensions of the magnetic base on which the layer is supported are compensated for by magnetising to saturation for part or all of the cycle, a part or the whole of the transformer core. An apparatus for the measurement of the thickness of tin coating on tin-plate is shown in Fig. 1. On a U-shaped magnetic core a are wound a primary winding b, supplied with alternating current, and a secondary winding c connected to a galvanometer d or other measuring instrument. A part of the core a is saturated by passing a direct current through a third coil e which current mav be derived from an accumulator or a rectifier e<SP>1</SP>. In a modification, Fig. 2 the current passed by a half-wave rectifier e<SP>1</SP> is used for both saturating current and primary current. The rectifier e<SP>1</SP> may be replaced by an accumulator so as to superimpose a direct current upon the alternating current through the primary coil. When a reading of the magnetic properties of the base material has been taken, the rectified or direct current is discontinued and the instrument used in the known manner to measure coating thickness, correction for magnetic properties being applied by means of a rheostat f with calibrater sliding contact. A change-over switch g enables the D.C. saturating current to be cut in or out. A backing- off current may be supplied in opposition to the current in the secondary coil in order to provide a set back zero. Instead of a U-shaped core, the transformer may have three parallel limbs magnetically linked, with primary or secondary coil on one limb and a secondary or primary coil on each of the other limbs arranged in series or parallel. For eliminating the effect of curvature of the magnetic base, each of the pole-pieces of the core may be formed as part of an ellipsoid of which the major axis may be inclined to the vertical.

Title: Improvements in or relating to the production of titanium pigments
IPC: C01G23/00
Filed: 1933-10-20
Abstract: Pigments comprising magnesium titanate are obtained by calcining together, say at 900 DEG  C., a titanium compound such as the oxide and a magnesium compound such as the oxide or hydroxide, the latter being present in any proportion up to but not substantially exceeding the theoretical amount required to form Mg2TiO4.  Extenders such as barium or calcium sulphate may also be present.  When using a hydrated titanium compound, it may be freed from sulphuric acid as by treatment with barium chloride or hydrate prior to calcination and before or after admixture with the magnesium compound or with the extender if one is present.  The presence of a small amount of hydrochloric acid accelerates the formation of the titanate, and calcination may be effected in the presence of a small amount of a salt such as sodium sulphate or carbonate, or with the addition of a small amount of phosphoric acid or a phosphate such as calcium or barium phosphate.  Numerous examples are given.  Specification 384,473 is referred to.  Reference has been directed by the Comptroller under Sect. 7 (5) to documents other than Specifications.

Classes 97 (i) and 97 (ii) In an angle-measuring instrument such as a theodolite, in which double lines are produced by forming in the plane of a graduation 3, Fig. 1, the image of a diametrically opposed graduation 31, four graduation lines, each separated by a right angle, are combined into double lines so as to obtain the mean of four reading positions simultaneously. The prism 7, which in conjunction with lenses 6 and prism 8 forms an image of graduation 3<SP>1</SP> which may be viewed by microscope 5, has an additional prism 10 cemented thereupon to avoid the numbering 41 of the graduation 3<SP>1</SP> causing a confusing image adjacent the numbering 4. The two sets of double lines are presented in the reading microscope as counter-running images as shown in Fig. 4, the images being displaced into coincidence by plane parallel plates or movable wedges, the corresponding image displacement being read off on accessory scale such as a micrometer screw. In a modification, Fig. 5, two sets of graduations are applied in a single operation by two dividing engines displaced against one another by half a right angle plus or minus half a line interval so that the lines of one graduation lie between those of the other. A line of one graduation, say 0, is then combined with the diametrically-opposed line 150a of the other graduation and presented as a counterrunning image to the double line formed from 100 and 250a. If the reading is repeated in the second telescope position the mean of eight reading places is obtained.
